Operators of California's electricity grid have declared a Flex Alert for Tuesday in an effort to reduce energy consumption.
The forecast peak demand is at extreme according to the California Independent System Operator and state grid operators are spreading the word that conservation will be critical.
San Diego Gas & Electric asked customers to reduce their use especially from 11 a.m. to 6 p.m.
Customers who do may be eligible for a credit on their bill.
To follow the flex alert guidelines, turn off all unnecessary lights, computers and appliances, postpone using major appliances until after 7 p.m. and turn your air conditioning thermostat to 78° F or higher.
The trend for Tuesday appears to be slightly cooler temperatures and lower humidity.
“Overall it won’t feel quite as sticky out there today but the temperature difference is just a few degrees,” said NBC 7 meteorologist Greg Bledsoe.
As for when San Diegans will get a break from the heat, the region should see temperatures drop slightly each day now through Thursday.
